Packers mum on Matthews' status

McCarthy not sure how long Pro Bowl LB will be out

The Green Bay Packers know what life is like without Clay Matthews, and they're bracing themselves again for being without their four-time Pro Bowl outside linebacker for an extended time after Matthews broke his right thumb during Sunday's 22-9 victory over the Detroit Lions at Lambeau Field.

Packers coach Mike McCarthy said in his usual day-after-the-game news conference Monday afternoon that Matthews was at a doctor's appointment being examined and that he was unsure how long his star defensive player would be sidelined.
